Effects of Different Types of Ceramic Fillers on Wear Characteristics of Glass Fibres-Epoxy Composite

Abstract

Experimental investigations had been done in this research to demonstrate the effect of glass fiber and Ceramic fillers contents on the tribological behavior of (15% volume fraction) glass-epoxy composite system under varying volume fraction, load, time, and sliding distance. The wear resistance was investigated according to ASTM G99-05 (reapproved 2010) standard using a pin on the disc machine to present the composite tribological behavior. The influence of three ceramic fillers granite, perlite, and calcium carbonate (CaCO3) on the wear of the glass fiber reinforced epoxy composites was investigated under dry sliding conditions. The effect of variants in volume fraction applied load, time, and sliding distance on the wear behavior of polymer composites is studied by the applied pin–on–disc method. In the experiments with a wear test pin having a flat face in contact with a hardening rotating steel disc, sliding speed, time, and loads in the range of 200 RPM, 300–900s, and 40–60 N respectively were used. It is observed that the wear resistance increase with the increase of reinforcement material volume fraction while, the wear rate increases with increasing applied load, time, and sliding distance. The results showed that the filler of granite, perlite, and CaCO3 as filler materials in glass-epoxy composites will increase the wear resistance of the composite by 76.15%, 73.8%, 71.8% respectively, and greatly than glass fiber fillers epoxy composite only and granite filled GE Composite exhibited the maximum wear resistance.
